Abstract

Die vorliegende Erfindung betrifft ein Zugregelverfahren für einen sich zwischen einem vorderen und einem hinteren Walzgerüst (2, 3) einer Walzstraße befindlichen Walzgutabschnitt (5) eines Walzguts (1). Um auch auch bei geringen Gerüstabständen und hohen Walzgeschwindigkeiten eine zuverlässige Zugregelung zu ermöglichen, ist vorgesehen,

  • daß ein Spannelement (6) mit einer Ist-Anstellkraft (F) an den Walzgutabschnitt (5) angestellt wird, so daß der Walzgutabschnitt (5) von dem Spannelement (6) um eine Ist-Auslenkung (z) ausgelenkt wird,
  • daß die Ist-Anstellkraft (F) und die Ist-Auslenkung (z) erfaßt werden und
  • daß ein zwischen dem vorderen und dem hinteren Walzgerüst (2, 3) in dem Walzgutabschnitt (5) herrschender Zug (Z) derart eingestellt wird, daß die Ist-Anstellkraft (F) sich einer Soll-Anstellkraft (F*) und/oder die Ist-Auslenkung (z) sich einer Soll-Auslenkung (z*) annähert.

The invention relates to a tension control method for a rolling stock section (5) of a rolling stock (1) located between a front and a rear rolling stand (2, 3) of a rolling train. In order to enable reliable tension control even with small stand distances and high rolling speeds, it is provided that
  • that a clamping element (6) is set to the rolling stock section (5) with an actual setting force (F), so that the rolling stock section (5) is deflected by the clamping element (6) by an actual deflection (z),
  • that the actual setting force (F) and the actual deflection (z) are detected and
  • that a between the front and the rear rolling stand (2, 3) in the rolling stock section (5) prevailing train (Z) is set such that the actual positioning force (F) is a target positioning force (F *) and / or Actual deflection (z) approaches a target deflection (z *).
